Wynn's Lead Substitute - Protects Against Wear in Unleaded Petrol Engines - Prevents Oxidation, Fuel Degradation & Deposit Formation - Suitable for 2-Stroke & 4-Stroke Engines - 250ml

Free Shipping

Why We Love It

Protects valve seats effectively.
Prevents fuel oxidation efficiently.
Works with various engine types.

Main Highlights

✅ VALVE SEAT PROTECTION FOR UNLEADED PETROL ENGINES: Ensures optimal protection for valve seats in engines that run on unleaded petrol. In the absence of lead, which previously served as a natural lubricant, this formulation replicates the same protective effect by forming a resilient lubricating coating on valves and valve seats. This artificial barrier significantly reduces friction and wear, particularly in soft valve seats, preventing the formation of micro-welding caused by high operating temperatures and pressures. As a result, engine longevity is enhanced and performance remains consistent, even under demanding conditions.
✅ PREVENTS PREMATURE WEAR IN CLASSIC AND MODERN ENGINES: Specifically designed to guard against the premature deterioration of soft valve seats in engines fuelled with unleaded petrol. The formulation creates a durable protective layer that mimics the lubricating properties of lead, reducing metal-to-metal contact and the risk of pitting and micro fusion. This protective action ensures that internal components maintain their integrity longer, helping to prevent performance issues and costly repairs.
✅ OXIDATION PROTECTION FOR LONG-TERM STORAGE: Provides a vital layer of defence against fuel degradation during periods of inactivity. When engines are not in use for extended durations — such as during winter or seasonal storage — fuel left in the tank is prone to oxidation. This process can produce sticky residues and corrosive by-products that lead to blockages in fuel lines, filters, and injectors. The advanced chemical composition of this product stabilises the fuel, preventing oxidation and extending its usable life.
✅ KEEPS FUEL SYSTEMS CLEAN AND EFFICIENT: Designed not only to protect but also to maintain the cleanliness of the entire fuel system. By preventing the formation of oxidation residues, this product avoids the build-up of deposits in the tank, filter, and carburettor, which could otherwise compromise fuel flow and combustion quality. Cleaner fuel systems contribute to improved engine efficiency, reduced emissions, and smoother performance. The stabilising agents work continuously to preserve fuel clarity and quality, especially in older or infrequently used machines where contamination risks are higher. Compatible with all petrol-powered two-stroke and four-stroke engines.
✅ VERSATILE USE FOR MULTIPLE ENGINE TYPES: Suitable for a wide range of petrol engines including those found in motorcycles, classic cars, lawn mowers, scooters, generators, and marine equipment such as yachts and outboard engines. Whether for recreational, domestic, or utility purposes, this additive enhances engine durability and fuel stability across all applications. Its protective formula ensures consistent performance regardless of engine size or usage frequency, making it a reliable choice for both daily drivers and seasonally operated machines.

Free Shipping

Why We Love It

Elevates engine performance significantly.
Ensures efficient fuel consumption.
Helps pass emission tests.

Main Highlights

✅ HIGH-PERFORMANCE PETROL ENGINE BOOSTER: Wynn's Formula Gold High-Performance Petrol System Treatment is designed to enhance engine performance by improving combustion immediately. A more efficient combustion process results in better acceleration, smoother engine operation, and reduced engine noise. By optimising fuel burn, the treatment contributes to a more responsive driving experience and minimises power loss over time. Ensuring a cleaner and more effective fuel burn not only improves engine longevity but also helps maintain optimal performance levels, making it an ideal addition to any vehicle maintenance routine.
✅ FUEL EFFICIENCY & CONSUMPTION REDUCTION: This advanced formula actively works to lower petrol consumption by optimising the fuel system's efficiency. By cleaning and maintaining fuel injectors, the treatment ensures a precise air-fuel mixture, which directly leads to improved mileage and reduced fuel wastage. The result is a more cost-effective driving experience with fewer trips to the petrol pumps. Over time, continuous use helps prevent build-up in the injection system, allowing the engine to operate with maximum efficiency, reducing the strain on fuel components and prolonging their lifespan.
✅ INJECTION SYSTEM CLEANING & PROTECTION: A clean fuel system is essential for maintaining vehicle performance and efficiency. Wynn's Formula Gold Petrol System Treatment actively cleans and protects the entire fuel injection system, preventing deposits from forming on critical components such as injectors, intake valves, and combustion chambers. A well-maintained injection system allows for smoother fuel delivery, preventing engine hesitation and misfires. By continuously safeguarding these components, the treatment ensures that the vehicle maintains optimal power output while extending the life of the fuel system.
✅ REDUCTION OF HARMFUL EMISSIONS: Designed to contribute to a cleaner environment, this treatment significantly reduces harmful exhaust emissions such as carbon monoxide (CO) and hydrocarbons (HC). By promoting more complete combustion, the formula helps decrease the production of toxic gases, making it an ideal solution for those aiming to meet stringent emissions regulations. Regular use can assist in passing MOT emissions tests by lowering pollution levels and ensuring the engine operates within regulatory standards. A cleaner exhaust system means less impact on the environment and improved air quality.
✅ SAFE FOR CATALYTIC CONVERTERS & ALL PETROL ENGINES: Wynn's Formula Gold Petrol System Treatment is formulated to be completely safe for use in all petrol engines, including those equipped with catalytic converters and modern exhaust after-treatment systems. Unlike harsh additives that can damage sensitive engine components, this treatment is carefully engineered to enhance performance without causing harm. Suitable for both older and newer vehicles, it provides a versatile solution for maintaining engine efficiency. For optimal performance, it is recommended to use this treatment in every third tank of fuel to continuously benefit from its cleaning and protective properties.
